E3D Hermes

IIRC Sanjay sad they are looking to put in lighter motors in later iterations.

Cela devrait bientôt être annoncé à grande échelle

Now available for sale, but under another name (perhaps a problem with the Hermès Paris brand). I look forward the comments on how it works.

@Rudy2A it was a certain delivery company that threatened legal action the day before they were due to launch

c'est une société de livraison qui a menacé d'intenter une action en justice la veille de son lancement

The day before its launch ... So that means that there is a series engraved "Hermes" no?

This new thing looks great, but it looks like the heat break just screws into the heatsink, the same as the V6. Did they do anything to secure it in the heatsink?

I've had the heat break come loose from the V6 hot-end many times during prints, screwing up the print quality. There is no way to securely mount the heatbreak in the heatsink- there's nothing to grab with a wrench on either the heatsink or the heatbreak, and no set screws. You can't twist it in by grabbing the heater block because the throat of the heat break is so thin it will break.

Given the reputation of "Hermes" the delivery company, changing the name on E3D's part was probably a good move

... more powerful motor than needed, to cater for electronics where setting accurate motor currents was difficult.

That's a good explanation. Sanjay was vague about the reasoning.

I wonder if a half size stepper with a passive non moving adapter to achieve the required inductance, resistance, and current for lesser electronics would work.

Should work. Hardest part is sourcing a module 0.25 22t gear with 0.5mm shaft ID. The one on the hermes appears to be made in house by e3d on their Swiss lathe. It’s press fit on the shaft

I really like my Delta, will it be compatible with the Smart Effector?

I'll be ordering one if it is. otherwise, I'm not giving up the smart effector for this, as much as I want direct drive extruder.

I can't see how it would mount in any compatible fashion. And, the adjuster thumbwheel sticks up. And, do we really want all that weight. And...

In short: Sure looks like it absolutely does not fit a Smart Effector.

I'm sticking with my BMG and Bowden, for the moment.

This. I have raged so hard about this many times before. It would have been the easiest thing in the world for them to add a set screw in the heatsink that tightens agaínst the upper part of the heatbreak that has no threads on it.
This is what i have done in the new extruder that i built, and it works like a charm.
But in general the whole e3d design is flawed with the unsupported heatbreak.
